Will.You.Type.With.Me

Will.You.Type.With.Me is a great online collaboration service. It is very similar to services such as Zoho Docs and Google Docs however it requires no login. You can only do text editing. On the side you will be able to see how many lines have been written and it is great for working together on an HTML. You can chat from a side bar and your revision history will be saved.
